World Maker Faire at the New York Hall of Science in Queens is the once-a-year DIY science fair that New Yorkers love. Flame throwing robots, giant Tesla coils that play music, learn-to-solder workshops, giant 3D printers, blinky art, and probably a Diet Coke and Mentos fountain performance -- a perennial crowd favorite.
If you're near New York City, come say hi this weekend, September 23rd and 24th. We'll be at the Craftacular section of the show, booth #55.
